The "moving wall" represents the time period between the last issue
available in JSTOR and the most recently published issue of a journal.
Moving walls are generally represented in years. In rare instances, a
publisher has elected to have a "zero" moving wall, so their current
issues are available in JSTOR shortly after publication.
Note: In calculating the moving wall, the current year is not counted.
For example, if the current year is 2008 and a journal has a 5 year
moving wall, articles from the year 2002 are available.

Terms Related to the Moving Wall

Fixed walls: Journals with no new volumes being added to the archive.

Absorbed: Journals that are combined with another title.

Complete: Journals that are no longer published or that have been
combined with another title.

Abstract

Integrated, long-term, ecological, hydrological, and biogeochemical studies have been done at the Hubbard Brook Experimental Forest since 1963 using the small watershed-ecosystem approach. Some biogeochemical results from these long-term studies, collectively called the Hubbard Brook Ecosystem Study, are described here, including approaches used for managing this large and complicated project. Some major biogeochemical findings of the Hubbard Brook Ecosystem Study are discussed briefly, including acid rain, and some biogeochemical research questions, opportunities, and challenges for the future are identified, including a recent whole-watershed addition of calcium silicate, weathering processes, and long-term trends in stream-water nitrate concentrations.
